> The single biggest change is the requirement to have some delimiter(s)

> patch 2/9 have changed considerably.

> There are a few ways to examine the changes since v5. My public repo at
> [6] has branches topic-parse-time-string-v5 (rebased to master) and
> topic-parse-time-string-v6, and [7] should provide a fancy colorful diff

> Change by change commits to the parser and test tool can also be found

> 3/9.
